This article talks about a recent tuition hike across public universities and how that affects diversity on a campus. For every $1000 that an institution raises their tuition they can expect to see a cumulative diversity drop in their student population of 2.6% of average. This is for public colleges, but you can expect a variance depending on the type of school. This is detrimental to not just the diverse population, but it is thought that having diversity at the school is linked to a boost in cognitive development.
